Objective: To examine differences in antibiotic susceptibility of Gram negative bacteria and in antibiotic consumption in a Tertiary Hospital, within 7 years of operation.

Methods: All clinical samples from inpatients. Identification and susceptibility testing, using the Wider® semi-automated system with CLSI breakpoints. Antibiotic consumption expressed as Defined Daily Doses (DDD) per patient-day.

Conclusion: Non-susceptibility rates of Gram negative bacteria markedly increased within 7 years and PDR strains emerged. This paralleled the increased consumption of wide-spectrum antibiotics (mainly Carbapenems and Fluoroquinolones) and of antibiotics used as last-resource (Colistin).
